Abstract: The invention relates to a device which is inserted into the mouth so as to isolate the dental part or area of the mouth to be treated, allowing improved vision, preventing the cheek and the tongue from impinging on the working area, and protecting the tissues of the patient from the dental instruments. Furthermore, the sucking capacity of the device prevents the saliva or any other fluid generated during the treatment from affecting both vision and the performance of a correct technique for carrying out the dental treatment.

Abstract: Medical or dental instruments, preferably handpieces, can have different temperature-measuring devices for measuring the temperature in the instrument or of at least a part of the instrument. The temperature-measuring devices can be designed, for example, to measure the temperature contactlessly by detection of electromagnetic radiation or to measure the temperature of an interior of the instrument that can be heated by a heat source. The temperature-measuring devices may be designed, for example, as electrical temperature-measuring devices or may have a magnetic material whose magnetic property is a function of temperature and/or has a temperature-dependent course. The temperature-measuring device may have, for example, an electrical switching device and a signal device wherein the signal device is switched at least between a first signal condition and a second signal condition when a temperature limit value is reached or exceeded or is underrun.

Abstract: A cosmetics carry system include a carrier that has an elongate body with openings at the opposite ends of the elongated body. At each end there are retaining features to non-permanently retain a small container of product in each end of the carrier. The containers can include a cap having an applicator that extends into the container. The retaining features are designed to allow the user to change the containers carried in the carrier so that the user can, for example, match color for lip gloss and nail polish. The carrier is a permanent member that can have decorative artwork on the outside, while the containers that are carried in the carrier can be disposable.

Abstract: Apparatus, system, and methods for utilizing one or more computing devices to stage the movement of teeth during an alignment treatment are disclosed. The computing device receives an electronic representation of the patient's teeth in their initial position and an electronic representation of the teeth a final position for each tooth. A route each tooth will travel to reach its final position is determined, and the teeth are scheduled to move according to a movement pattern. Moreover, the schedule of movement takes into account a maximum rate of tooth movement for each tooth, the path of movement for each tooth, the distance each tooth needs to move, any needed tooth staggering, any needed round-tripping or tooth movement slowing. The invention also includes techniques for determining an optimum number of stages for the treatment based on the schedule of movement.
